Abstract
Taking one fault diagnosis on abnormal increase of dielectric loss of 500 kV main transformer oilpaper capacitance casing pipe as an example,this paper introduces a kind of abnormality diagnosis method for dielectric loss of the main trans-former oilpaper capacitance casing pipe based on heat stability. By testing for heat stability performance,law of dielectric loss with change of temperature was obtained and reason for abnormal dielectric loss was diagnosed according to heat stabili-ty theory. Effectiveness of this method for diagnosis on insulating medium affected with damp was verified.关键词
